Abstract

Les modes de réalisation de la présente divulgation concernent des procédés, des dispositifs et des supports de stockage lisibles par ordinateur pour une resélection de ressources dans une communication de véhicule à tout (V2X). Le procédé consiste à : déterminer, au niveau d'un dispositif terminal, une période de réservation de ressources pour au moins une transmission de liaison latérale; et conformément à une détermination, d'après la période de réservation de ressources, selon laquelle une ressource de référence associée à la transmission ou aux transmissions de liaison latérale est consécutive à une fenêtre de détection, déterminer, à partir d'une fenêtre de sélection de ressources du dispositif terminal, au moins une autre ressource de référence à réserver pour la ou les transmissions de liaison latérale d'après la période de réservation de ressources. De cette manière, le conflit de sélection de ressources peut être évité et, par conséquent, les performances de la transmission de liaison latérale peuvent être améliorées.
